not able to run testng test from ant.

[ajay mehra]

I have a testng test called Introduction50.java,an xml file for it
(Introduction50.xml) and an ant script(Introduction50_ant).
when i run this test through the command line using ant:

i get some error like this:

So could you plz tell me wht could be the pblm and i would really
appreciate if u can provide me the solution.

[Karthik Krishnan]

Can you run your failed unit test from any IDE using TESTNG plugin ?


If it runs successfully, can you post the test class and ant script? The problem may lie in the way you define data providers or something like that. This is just speculation not knowing your code

[Cédric Beust ♔]

No, I think it's just a classpath problem, based on the error.  Just make sure your classpath is configured correctly.

When i ran my testng script in eclipse,it worked.but i am facing difficulty in ant.so could you plz rectify wht i hv done wrong here.

This is my testclass with ant script.

My testclass  as folows:(SimpleTest.java)
package example1;

public class SimpleTest {

 @BeforeClass
 public void setUp() {
   // code that will be invoked when this test is

 }

 @Test(groups = { "fast" })
 public void aFastTest() {
   System.out.println("Fast test");
 }

 @Test(groups = { "slow" })

You need to check your classpath.... What happens if you try to compile SimpleTest with your classpath reference?

[ajay mehra]

could u plz tell me hw to set a classpath for a class because i am getting confused with this.

This is a beginner Java question, please do a Google search on it, there is plenty of material available.

[ajay mehra]

i did that and i knw hw to set a class path by adding the path in environment varialbles but m still getting the same error that i hv mentioned above in my tests.

2009/9/15 Cédric Beust ♔ <cbe...@google.com>

[Karthik Krishnan]

I am not talking about setting classpath with your environment variables. In Ant, we can compile using javac where you can set up classpath reference id.

[ajay mehra]

sir can u plz send me a simple testng test with itz ant script and the way we run this testng script using ant so that i can know  where am i goin wrong. and it would be of gr8 help to me.

[Tarun K]

See the place where u have class name in testng xml file -

**************************

<classes>
<class name="SimpleTest"/>
</classes>

**************************

Provide full qualified name for class. To know qualified name for
class, just right click on class in Eclipse and select "Copy Qualified
Name". It might be some thing like - "com.test.SimpleTest.java".
REMEMBER to remove ".java" extension
hence class name would be like - "com.test.SimpleTest"

Now try. Any ways this should not have worked in Eclipse as well (what
u claimed earlier)

[ajay mehra]

my testng class i.e(SimpleTest.java),xml file(SimpleTest.xml) and the ant script are at the same place i.e (c:\testng-5.9\apache-ant-1.7.1\lib). but still i get the error: could not instantiate SimpleTest.
                                                                                             cannot find class in clsspath:SimpleTest

[Tarun Kumar Bhadauria]

Did you try what I suggested….

 

Thanks,

[ajay mehra]

yes i did tat but let me tell you one thing that i am not using eclipse.itz through ant on command prompt

[ajay mehra]

 the command that i am using to run this test is:java -classpath ant.jar;ant-launcher.jar -Dant.home=apache-ant-1.7.1 org.apache.tools.ant.launch.Launcher -buildfile SimpleTest_ant.xml

[Tarun Kumar Bhadauria]

Even then u must know “hierarchy of class”… I hope u understand what “full qualified name” of class mean….

[ajay mehra]

My class SimpleTest is inside c:\testng-5.9\apache-ant-1.7.1\lib\SimpleTest.java and i must say this is the hierachy of my class so do i need to give the full path of class inside the xml file.

[Tarun Kumar Bhadauria]

You have java class in “lib” folder… It should be in “src” folder…

[ajay mehra]

i ran even from src but it still shows me the same error.

[Tarun Kumar Bhadauria]

I give up… please consult a dev in your team…

[ajay mehra]

sir can u give me ur gtalk id so that i can clearly explain wht i hv done.and i think i might hv done some mistake whick could be resolved by you.

thank you sir for trying to help me....i wil mail u to ur mail:TBhad...@ciber.com.

Hi,
    how can we pass different kinds of parameters with dataproviders to a test method.can anyone post a good example of parameters with dataprovider.

Here is a sample test incorporating a DataProvider

Hi sir,
 i have two test methods and i made one test method dependent on other method by giving annotation dependsOnMethods,so wen i run it executes the main method and skips the dependent method.why itz happening like this.

[ajay mehra]

Hi All,
how can we do parameterization for python tests??

[ajay mehra]

can anyone help me how we can launch our testNG test using ant.till now i was executing my testcases in the commandline and it was succesfull.and i dont have any idea about how to make a ant script for my testng tests to launch it with ant.so if possible please provide me a sample ant buildfile so that i can implement it in my testNG test.
the version of ant i am using is apache-ant-1.7.1 and my testNG version is testNG-5.9.

Guessing ...
(because without seeing exactly what your file looks like, it's quite
hard to know.)

I'd guess it means you have added a "fork" attribute to your <testng>
command in your Ant file.
i.e. something like <testng fork="true" ... >

The supported attributes are listed on http://testng.org/doc/ant.html
Please read it. It doesn't mention a fork attribute, it says that
TestNG ALWAYS runs in a forked JVM, so one isn't needed.

how can we schedule our testng testcases from ant?

[Karthik Krishnan]

Schedule test runs as in have them run at a particular time....

[Harihara Vinayakaram]

We have been using Hudson. You can define a job and have this scheduled

Hari

[ajay mehra]

i want my testng testcases from to run from at a particular time like it must run at night 9 pm say.so is there any way where i can configure my ant script to run at that time.i heard about scheduling  but dont have any idea how it is used in the ant buildfile.

You wouldn't normally schedule from within ant. If you do continuous
integration, then the documentation for your CI server will tell you
how to run an ant task on a schedule. It'll also publish the results,
often by email. If you can do continuous integration, I'd strongly
recommend it.

Without a CI server, you probably want to use some kind of scheduling
utility for your operating system. In Linux or Unix, that would be
cron. Other Operating systems use different mechanisms.

The trick with a scheduled ant run is to publish the results - but ant
provides tools that will let you do that...

[ajay mehra]

well i have lotz of testcases and i want them to run at different time with the help of ant.so my question is does ant provide any feature like this.

[Bill Michell]

Ant will help you control *which* test cases run, but not *when* they run. Ant isn't designed to be a general purpose programming language or a scheduling system. I suppose in theory you could write a scheduler task to embed within ant - but why? It would be like using a toothbrush to brush your hair. You might be able to achieve the result, but it is totally the wrong tool for the job.

It sounds like you need a continuous integration server, like Hudson or CruiseControl or any number of other solutions.

Even if you don't do Continuous Integration, the CI servers are good at running ant commands according to a specified schedule, and distributing the results in an appropriate way.
